John,
Thanks for posting this event here and on MJ. All your help with enlisting participation is appreciated....not to mention, the Kaiser can hold a lot of roofing shingles/trash Your involvement has been a great help!

I would also like to note that this trail clean-up is put on and organized every year by the Two Trackers 4WD Club based out of Grand Rapids, MI. We have been doing this for the past 10 years, 5 or more within the Muskegon County Area. For more information, you can visit the club at: http://twotrackers.org/ Beware the pop-ups
